Many elevator devices are configured to connect an elevator car and a balance weight on which a user rides with a hoisting rope wound around a hoisting machine, and to move the elevator car up and down by balancing the weight with the balance weight. Yes. This is called a rope elevator.
[0003]
By the way, in such a device, as a space in the building where the elevator is installed, a hoistway in which the elevator car moves up and down and a machine room for storing the hoisting machine and the control device are necessary. It is installed on the roof of the building, and the maintenance work of the elevator is mainly performed in this machine room.
[0004]
On the other hand, an elevator apparatus that does not require a machine room for installing a control panel has been proposed as disclosed in JP-A-59-163270. That is, a method has been adopted in which an elevator control device is installed in the vicinity of a landing or in an elevator car, and the hoisting machine is stored in the upper or lower part of the hoistway.
[0005]
For example, the depth of a door pocket, which is an elevator door storage part on one floor, is made larger than the other floor part to form a storage part, and the elevator control device is stored in the storage part. The hoisting machine is downsized and thinned so as to be disposed in the empty space at the top or bottom of the elevator hoistway.
[0006]
FIG. 11 is a diagram showing a schematic configuration of an elevator apparatus in which a machine room is omitted. In the hoistway 1, a pair of left and right main guide rails 2a and 2b (2a in the figure) provided on the hoistway wall surface. The elevator car 3 is disposed so as to be movable up and down along a pair of auxiliary guide rails 4a and 4b provided on one side wall surface of the hoistway so that the counterweight 5 moves up and down. is there.
[0007]
A hoisting machine mounting base 6 is attached to the main guide rail 2a, and a hoisting machine 7 is installed on the hoisting machine mounting base 6. A rope hitch (not shown) provided in the hoistway 1 is provided with one end portion of the suspension rope 8 wound around the hoisting machine 7 turned upward via a turning sheave 9 provided on the lower surface of the elevator car 3. The other end is turned upward through the turning sheave 10 of the counterweight 5, and the top end is connected to the rope hitch 11.
[0008]
On the other hand, a control device 13 for controlling the operation of the elevator is provided near the landing door 12 on the specific floor. In the figure, reference numeral 14 denotes a car door.
[0009]
FIG. 12 is a cross section of the hoistway 1. The elevator car 3 is supported by a main rope 8 engaged with two turning sheaves 9, 9 provided on the lower surface of the elevator car 3. A counterweight 5 is disposed on the back side of the main guide rail 2a between the side surface of the elevator car 3 and the hoistway wall. As a result, the hoistway can be realized only by the size of the elevator car 3 and the size of the hoisting machine 7.
[0010]
FIG. 13 is a view showing the appearance of the floor side of the floor where the control device 13 is provided, FIG. 14 is a plan sectional view thereof, and the doorway for storing the landing door 12 is placed in the landing three-way frame 15. A control device housing chamber 17 is formed in the front part of the section 16, and the control device 13 is stored in the control device housing chamber 17. A control device door 18 is provided on the front surface of the housing chamber 17 so as to be openable and closable. Yes. Further, a landing operation panel 19 is provided on the opposite side of the control door 17 from the landing door 12, and the elevator user calls the elevator car by pressing the call button on the landing operation panel 19. Can do.
[0011]
However, in this configuration, since the elevator control device 13 is installed near the landing used by the elevator user, when the control device door 18 provided in the landing three-way frame 15 or the like is opened by mischief or the like, the control is performed. The person in the elevator car 3 as well as the person who opened the device door 18 may be in a dangerous state. That is, when an operation such as turning off the power of the elevator control device 13 is performed due to mischief or the like, there is a possibility that the elevator car stops even while traveling and the users in the elevator car are confined.
[0012]
In addition, since the conventional rope type elevator works in the machine room, it was possible to proceed safely without a third party entering during the work. A dedicated maintenance person needs to open the control device door 18 and perform maintenance work. Therefore, since the control device 13 is in contact with the elevator landing, it is necessary to work in a place where building users, that is, passengers and passersby come and go, which is dangerous. The control device 13 is normally applied with a voltage of about 3V 200V, so that a child or the like may inadvertently come into contact with the device to get an electric shock, and the maintenance staff may be in danger. Can also be a big problem.
[0013]
In order to prevent these problems, a control device door key 20 or the like is attached to the control device door 18 to prevent the control device door 18 from being easily opened by a third party, and when the control device door 18 is opened. Safety is enhanced by providing an open / close detector 21 and an operation circuit for detecting the door open / close state so as to stop the elevator.
[0014]
[Problems to be solved by the invention]
However, when the control device is stored in the three-way frame door pocket, the depth of the storage part is larger than that of other floors as described above, and measures against mischief against third parties are taken, so the degree of freedom in the design of the platform There are some restrictions. That is, even if it is desired to adopt a design that does not have a three-way frame, it is necessary to provide a three-way frame on the floor where the control device is installed.
[0015]
On the other hand, if the control device is installed in the pit at the bottom of the hoistway, there is a possibility of flooding due to a typhoon or the like.
[0016]
In view of these points, the present invention installs a control device as a main control unit in a three-side frame on the landing side and in a hoistway space other than the lowermost part of the hoistway to improve the design freedom on the building side. The first purpose.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the figure, the same parts as those in FIGS. 11 to 14 are denoted by the same reference numerals, and detailed description thereof is omitted.
[0028]
1 to 3 are views showing a first embodiment of the present invention. As shown in FIGS. 1 and 2, one of the main guide rail 2a and the hoistway 1 is provided on the back side of the main guide rail 2a. A hoisting machine 7 is disposed between the side inner wall surface. A space corresponding to the thickness of the hoisting machine 7 formed between the main guide rail 2a and the counterweight guide rail 4a for weight balancing and the inner wall surface of the hoistway 1 is constituted by a main control unit that controls the operation of the elevator. A control device 13 is installed.
[0029]
That is, as shown in FIG. 3, the main guide rail 2a is attached to one side inner wall surface 1a of the hoistway 1 by a plurality of rail brackets 25, and the rail brackets 25 are usually installed at intervals of 5 m. Yes. Therefore, the space section delimited by the rail bracket 25 is sufficient as a space for storing the control device 13, and is located between the main guide rail 2a and the inner wall surface 1a on one side of the hoistway 1 and the upper and lower rails. The control device 13 is installed between the brackets 25 via a support device (not shown).
[0030]
Thus, in this embodiment, the installation location of the control device 13 can be selectively determined from the space corresponding to the lift distance of the elevator car. In addition, when the control device 13 is provided on the inner wall surface of the hoistway as described above, the maintenance inspection is performed from above the elevator car. Even when the control device becomes larger in the height direction, the elevator car is not installed. By moving up and down, the optimal inspection position can be easily secured.
[0031]
In the above embodiment, the control device 13 is shown as one large component. For example, the control device 13 is divided into a plurality of control device sections according to functions such as a power supply section, a main circuit section, and a control circuit section. It is possible to configure each control device unit at a predetermined installation position.
[0032]
FIG. 4 is a view showing a second embodiment of the present invention, in which a support member 26 having an L-shaped cross section is fixed to the back surface of the counterweight guide rail 4a for counterweight, and a control device is provided on the support member 26. 13 is installed.
[0033]
That is, the space between the main guide rail 2a and the sub guide rail 4a is generally only about 200 mm, and if the control device 13 is directly fixed to the main guide rail 2a or the sub guide rail 4a, the subsequent maintenance may be difficult. . Therefore, in the present embodiment, the control device 13 is attached to the support member 26 fixed to the sub guide rail 4a as described above, and at the time of maintenance, the control device 13 is attached to the side of the main guide rail 2a (in the direction indicated by the arrow) ) Can be pulled out.
[0034]
In this case, since the maintenance of the control device 13 is normally performed from the elevator car toward the main guide rail 2a, the main guide rail 2a does not disturb the maintenance work.
[0035]
In the above embodiment, the support member 26 is fixed to the back surface of the sub guide rail 4a. However, the support member 26 may be fixed to the back surface of the main guide rail 2a, and the main guide rail 2a. It may be fixed to the rail bracket 25 for fixing. Furthermore, the support member 26 is not limited to the L-shape, and may be configured so that the control device 13 can be installed and pulled out to the side of the main guide rail 2a.
[0036]
FIG. 5 is a diagram showing a third embodiment of the present invention, in which the control device 13 composed of a main control unit that controls the operation of the elevator is a hoistway inner wall surface 1b on the landing side at the top of the hoistway. Are installed via attachment members 27.
[0037]
Thus, in this configuration, the space at the upper part of the landing side at the top of the hoistway can be used effectively, and the front surface of the control device 13 is not obstructed by a maintenance surface such as a guide rail. Can be safely maintained and inspected by the operator on the car while the vehicle is stopped near the position on the top floor.
[0038]
6 and 7 show the fourth embodiment. The basic configuration is the same as that of the third embodiment, but maintenance and inspection can be performed from the landing side.
[0039]
That is, one end of a support arm 28 is mounted on both sides of the control device 13 so as to be swingable around a horizontal axis, and the other end of the support arm 28 is connected to the hoistway inner wall surface 1b on the landing side at the top of the hoistway. It is pivotally attached via a shaft 29.
[0040]
Therefore, in a normal state, the control device 13 is fixed vertically to the hoistway inner wall surface 1b on the landing side at the top of the hoistway, as indicated by a dotted line in FIG. Therefore, at the time of maintenance inspection, the support arm 28 is rotated around the shaft 29 as shown in FIG. Therefore, the control device 13 can be rotated while maintaining the vertical state and pulled out to the landing entrance space as shown by a solid line in FIG. FIG. 7 shows a state in which the control device 13 is moved to the maintenance inspection position as seen from the landing side.
[0041]
As described above, in the present embodiment, by changing the position of the control device 13 between the normal time and the maintenance time, it is possible to achieve both normal time and maintenance workability. In other words, since the control device 13 is normally housed in the hoistway, there is no risk of being exposed to tampering by a general user. On the other hand, the control device 13 is pulled out to a position that can be inspected from the landing side during maintenance. Compared with, inspection can be performed in a bright place, and work efficiency can be improved. In addition, the wiring from the inside of the control device 13 to the outside can be prevented from causing stress due to the rotation operation of the control device by laying along the support arm 28.
[0042]
On the other hand, an operation panel can be provided on the landing side in order to enable remote control of the control device 13. FIG. 8 is a front view of the operation panel 30. The operation panel 30 can be used for functions such as a status display unit 31 for displaying the status of the elevator, and reference and change of internal data of the control device 13. For example, an operation button group 32 such as a mode switching button, a selection button, and a determination button, and an operation switch group 33 for operating operations such as raising / lowering of the elevator, door opening / closing, inspection / normality, etc. There is provided a data output terminal 34 capable of setting an output of a digital signal such as a limit switch or an analog waveform such as the speed of the elevator car. The operation panel 30 is normally covered so that only an elevator maintenance specialist can operate it.
[0043]
Therefore, when the control device 13 is operated, it can be remotely operated using the operation panel 30, and the control device 13 can be operated without going to the vicinity of the control device 13.
[0044]
In the above-described embodiment, the control panel remote control operation panel 30 is provided on the landing side, but the optical communication connection terminal 35 as shown in FIG. 9A is provided on the landing side. By inserting and connecting the optical communication cable 37 attached to the elevator maintenance device 36 shown in (b) to the optical communication connection terminal 35, the control device 13 is remotely controlled by the elevator maintenance device 36. It may be.
[0045]
FIG. 10 is a diagram showing an appearance of the maintenance operation switch 38 installed in the vicinity of the entrance of the service entrance, for example, in order to realize the maintenance operation. The maintenance operation switch 38 is a switch of the same system as a parking switch that has been used conventionally, and is installed, for example, in the vicinity of a landing at a common entrance as described above.
[0046]
Accordingly, the elevator operation mode can be switched by inserting the key switch carried by the maintenance worker into the key groove 39 of the maintenance operation switch 38 and switching the key position.
[0047]
That is, the parking operation is started when the position that is in the RUN (normal) during normal operation is switched to PAK (parking).
[0048]
Also, when the maintenance operation switch 38 is set to CALL (call back), the maintenance operation is started, and after responding to the registered car call, the elevator car is pulled back to the floor with the entrance, and the door is opened after stopping. It becomes a state.
[0049]
Thus, when the position is set to CALL, the elevator car is in a standby state when the door is opened, so that there is no fear that the elevator car is inadvertently pulled back by a third party operation during maintenance work.
[0050]
Also, when the maintenance operation switch 38 is set to the MNT (maintenance) position, the on-car inspection position movement operation is started, and the inspection speed (about 15 m / min) is reached from the entrance to the position where it is easy to get on the elevator car. The elevator car moves and stops. After that, the operation is on standby in the inspection operation mode. On the other hand, when the elevator car is switched to MNT (maintenance) while traveling, after the elevator car has been pulled back to the floor with the service entrance, it will move to the above inspection position on the car The operation is performed.
[0051]
In this way, by providing the maintenance engineer operation switch, the elevator car automatically moves to an appropriate position for carrying out the inspection on the car. be able to.
[0052]
Further, the maintenance operation switch 38 can be installed not only on the service port but also on a floor near the height where the control device 13 is installed, for example. In this case, normal return from maintenance work can be performed smoothly. In other words, if a maintenance person who has entered the elevator car at the common entrance travels in the hoistway and finishes the inspection of the control device 13 and gets off at a nearby landing, the position of the operation switch 38 for maintenance is quickly changed to RUN ( Normal).
[0053]
【The invention's effect】
As described above, according to the present invention, since the control device for controlling the operation of the elevator is disposed on the back side of the main guide rail or the sub guide rail, there is no risk of the control device being erroneously operated by a third party. In addition, the installation location of the control device can be selectively determined from the space for the lifting distance, and even if the control device becomes larger in the height direction, the elevator car can be moved up and down The optimal inspection position can be easily secured.
[0054]
In addition, when the control device is installed inside the hoistway at the top of the landing entrance on the top floor, there is no obstruction on the surface where maintenance of the control device is performed, so the elevator car is stopped near the top floor position. A worker on the car can safely perform maintenance and inspection of the control device. Furthermore, when the control device can be pulled down to the landing position on the top floor, there is no risk of being exposed to mischief by ordinary users during normal times, and it can be inspected from the landing side during maintenance and is brighter than the hoistway. There is an advantage that can be checked on site.
[0055]
In addition, the control panel for remote operation of the control device and a connection terminal for connecting a maintenance device are installed on the landing side, or the operation switching device for maintenance is provided near the landing on a specific floor.
